With the Bosch UniversalLevel 360, you can be sure that all paintings hang at the same height, without having to move the laser. This cross-line laser projects 360 degrees around a horizontal line, so you can easily attach tiles and shelves at the same height. To project the lines, this laser has 3 modes. Cross line mode, vertical mode, and horizontal mode. The green laser lines have a beam distance of 24m with an accuracy of 0.4mm per meter. The self-leveling range of approximately 4 degrees ensures the laser always levels the lines. You can also project lines at an angle. The UniversalLevel 360 works on 4 AA batteries and can be safely stored in the included storage bag after use.
